Bucket Ladder Dredgers

This type of dredger is also designed for the extraction of sand and gravel from wet mining pits and comes in both a land-based and floating type. The dredging depth of bucket ladder dredgers varies from 0 to 12 (or 14) metres for the land-based models and from 6 to 24 metres for the floating models. Similar to floating clamshell dredgers, floating bucket ladder dredgers are equipped with an on board processing plant comprising a double or single deck screening machine, crusher, fine sand recovery, conveyor belt or hydraulic transportation to shore.
